Spatial Analysis Portfolio
Introduction
This portfolio shows a series of maps created in R (except for the maps of Mumbai which were created in QGIS) demonstrating the following skills:
Displaying multiple vector layers on the same map
Calculating and displaying relationships among point and polygon layers based on distance
Aggregating point data to a layer of polygons
Calculating and displaying accessibility, based on travel time
Converting between raster layers and vector layers
Displaying raster data on a map
Georeferencing a raster image
Displaying data on an interactive map
The maps cover a range of cities and display data pulled from historical maps, OpenStreetMaps, local open data sources, US Census data, and more.
Cambridge, MA
Skills shown: Displaying multiple vector layers on the same map
This map of Cambridge, MA visualizes multiple vector layers: open space and schools in the town.
Mumbai, India
Skills shown: Displaying raster data on a map; Georeferencing a raster image
For an assignment on Georeferencing, a map of Mumbai from 1960 was brought into conversation with both historical and more recent data about the city.
